Social Lives of Monumental Walls: Hunting along the Upper Tigris
No full textOn the left bank of the Tigris in northern Iraq, in an area today partially flooded by the Mosul Dam reservoir, lies an enigmatic monumental enclosure known in the literature as the “Tigris Wall.” Before its partial submersion under the waters of the modern lake, the large L-shaped embankment, about 4 × 4 km long, enclosed an area of ca. 1600 ha, overlooking the Tigris and its alluvial plain. By means of a holistic strategy that includes different levels of analysis (remote sensing, pedestrian and UAV photogrammetric surveys, excavation, and settlement pattern analysis), this paper addresses the structure, its context, and its environment. Relying on the results of this multi-disciplinary approach, we present an updated and detailed discussion of the structure’s possible functions and interpretations. Parallels from northern Mesopotamia and neighboring regions are used to suggest that the Tigris Wall may be the first archaeologically known hunting park in the region, probably dating to the Late Sasanian or Early Islamic epoch
SGA children: auxological and metabolic outcomes. The role of GH treatment.
No full textThe definition Small for Gestational Age (SGA) describes those newborns weighing and/or
measuring in length52 SD than expected for their gestational age. These subjects are at
higher risk of short stature, neonatal complications, alterations of glucose, lipid metabolism,
body composition, bone metabolism and puberty, neurocognitive vulnerabilities and
alterations of the GH-IGF-I axis. With regards to growth, in 85–90% of the cases children
born SGA experience a period of catch up growth that allows them to achieve an adult stature
within normal range. In a 10–15% of the cases, the catch up growth period does not take place
and this entails short stature in adulthood. In the latter group, GH treatment may be considered
to achieve adult height in the range of genetical target stature. With reference to glucose and
lipid metabolism, young adults born SGA and particularly those with early catch up growth are
at higher risk of developing insulin resistance, type 2 diabetes mellitus, arterial hypertension,
dyslipidemia, overweight, obesity and metabolic syndrome. Subjects born SGA are in need of a
correct diagnostic and eventually therapeutic approach
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Ethical considerations for remote sensing and open data in relation to the endangered archaeology in the Middle East and North Africa project
No full textThe UK-based Endangered Archaeology in the Middle East and North Africa (EAMENA) project uses remote sensing techniques to rapidly record and evaluate the status of archaeological and cultural heritage sites in the MENA region. Applying remote sensing methods to the archaeological landscapes of 20 countries, EAMENA is one of the largest documentation projects of its kind. Such a scope raises important ethical questions fundamental to the practice of remote-sensed archaeology, and this paper contributes to this discussion by reflecting on EAMENA's unique role in this subfield. We present ethical issues and possible solutions related to remote sensing and archaeology, drawing on models developed within the humanitarian aid sector and postcolonial archaeology. In addition, we consider issues of national sovereignty and their relationship to the engagement of local communities. Finally, this paper examines the roles of data openness and open access policies as ethical factors and how EAMENA has addressed these so far
